Inexpensive Backup StorageThe product works as expected and provides 4 Gig of storage at a very reasonable price. The only negative - there is no indication that the drive is operating (flashing light or similar). That is not significant in my opinion and I am totally satisfied with this product.

Great for backup or extra data storageThis external HD was easy to setup and is very fast. The backup software that came with it is okay, but I may switch to the File History program in Windows 10. For some reason the Western Digital backup software seems to show more memory used than is actually used.

A VERY GOOD external Drive!This external drive is very good one, sleek, small in size, and it does transfer content really fast since it is USB 3.0 (and also works with the USN 2.0).
